I never said they should remove it. Never said they should stop you from roleplaying as a gay/bi character (heck, I had a FNV character who ended up having a crush on Veronica because I thought it would be a interesting twist for her story). What I'm saying is that an RPG that forces some background elements on your character for the sake of having a more fleshed out story doesn't make it any less of an RPG.
